cain and abel

so God favored Abel over Cain...but aren't we not supposed to show favoritism? and then cain killed abel.....dang. that's hardcore. so this isnt really about the reading but my parents were watching some dvd of a sermon some japanese guy gave, and one thing he points out is that God oftentimes chooses between brothers and this was one of his examples...its a very interesting observation, but i dont really remember how the guy applied it to nowadays, so i guess that rant ends here. this was the only part of the reading that really sparked interest in me today, probably because i skimmed through all the "this guy was this many years old and had a son who grew to be X years old" and the noah part was ehh, cuz we all know what happens with him. oh and also the way that God talks to Cain in this chapter, well at least the way its phrased makes it seem like God was standing there, like they were homie g's, or when he walks with Enoch until he's no more. How come he doesn't play the more distant, appear-in-the-burning-bush type God like he does later on in the Bible? These are just thoughts, well...questions that occured to me while I was reading.
